On the final day of the Time War, the Time Lords, now led by Rassilon, broke the time lock to materialise Gallifrey in Earth's skies in 2009, thinking the War Doctor would precipitate their ultimate demise on that final day through the Moment. However, the Tenth Doctor sent the planet, Time Lords included, back to its doomed fate, by breaking the link that brought the Time Lords to Earth. (TV: The End of Time)

Gallifrey was thought to have been destroyed by the Doctor in the Time War (TV: The End of the World, Dalek) but was frozen in time in a pocket dimension by the first thirteen incarnations of the Doctor. The vast majority of the Daleks died in the crossfire when Gallifrey disappeared. (TV: The Day of the Doctor)

In the original script of The Time Warrior, Gallifrey was scripted as "Galfrey", but was later changed.

Even though the first on-screen mention of Gallifrey was in The Time Warrior, broadcast in December 1973, the word appeared in TV Action #126, put out for the week ending 14 July 1973. There, in the letters column, the editors responded to a question from Simon Still of Kent who asked where the Master came from. The answer? "The Master's home planet was called 'Gallifrey'." This probably doesn't mean, however, that Polystyle gets the credit for "Gallifrey". Since shooting on Warrior wrapped on 12 June 1973, and the scripts had been completed earlier that spring, the likelihood is not that the TV Action originated the name, but that they were given it by the Doctor Who production office.
